An interview with Ryan Britt, the author of The Spice Must Flow, about Dune’s once-covert climate change message.
For someone who’s been hit by the Dune curse, author Ryan Britt was in good spirits when I spoke to him about his new book, The Spice Must Flow: The Story of Dune, from Cult Novels to Visionary Sci-Fi Movies, on Friday. “It has to be something, always,” he told me brightly, in reference to the second installment of Denis Villeneuve’s Dune adaptation — to which last week’s release of The Spice Must Flow had been loosely tied — getting delayed to next year due to the Hollywood strikes. Still, Britt winces at himself when he remembers he’s called Dune: Part Two a “2023 film” in print.
I imagine, though, that Britt’s readers will forgive him. The Spice Must Flow is a wonderfully enjoyable companion guide to Dune, including for people who aren’t really that deep into Arrakis lore (or haven’t, like me, read beyond Frank Herbert’s first book). Touching on everything from the nonfiction magazine article that was the earliest version of Dune, to the turbulent attempts to adapt the novel into a film, Britt also gives welcome space to how Herbert’s sandworm-populated, drugged-up sci-fi saga serves as “an ecological guide to the future.” Our conversation has been condensed and edited for brevity and clarity.
Where were you when you learned Dune: Part Two was being pushed back?
I was getting ready to make my six-year-old daughter dinner with my wife. I shouldn’t say that I was making dinner — I think my wife was getting ready to make dinner and I was helping and hanging out with my daughter. And I got a text from my literary agent just saying, “Had you seen this?”
But you know, I had seen the rumors that it was potentially going to happen. And just from an entertainment industry/publishing standpoint, it’s the most Dune thing that could possibly happen. I was joking with many people that writing a book about Dune is like — I'm entering into a world that was very hard for David Lynch and very hard for Frank Herbert and [Alejandro] Jodorowsky and Denis Villeneuve. Something always happens to people who are doing Dune projects. It was like, “Okay, so I don’t get to have a book out at the same time as the movie? I’m getting off easy compared to Lynch, who lost like four years of his life or whatever.”
You write that “the public perception of Dune as an ecological science fiction novel is perhaps the most important factor in its immortality.” But as you note in your book, Herbert didn’t exactly set out to write an ecological science fiction book. How did Dune gain the reputation of environmental literature that it has today?
I want to be careful about this because I think that it’s possible that Frank Herbert did have that intention. He dedicated the first novel to “dry land ecologists.” He began writing a nonfiction article about real sand dunes, and that led to writing Dune. I just don’t think that environmentalism was his sole intention or his sole motivating factor in completing the first book. By evidence in my research and the research of others, he played up that [intention] after it was claimed by environmentalists.
The big thing that happened is Stewart Brand’s The Whole Earth Catalog in 1968 picked Dune as an ecological text, and then Frank Herbert spoke at Earth Day in 1970. I actually brought with me as a prop the New World or No World (1970) book, which was based on a TV special Herbert did. [Reading from the book’s cover:] “‘Our ecology crisis and what to do about it,’ edited by Frank Herbert.” So this is where, by the end of the 1960s and early 1970s, Herbert really starts saying Dune was an ecological book.
And that’s definitely in the text. But at the same time, the planet ecologist who is the father of Liet-Kynes, Pardot Kynes — all of that is from the appendices that are in the novel but weren’t in the original serialized magazine versions. A lot of the big ecological ruminations are sort of covert in the first run. But even in New World or No World, where Herbert talks about putting the words of ecological concern into the mouths of his characters — that’s from the appendices. So I think that he was always throwing down a message about climate change and a message about how corrupt governments contribute to that, but he wasn’t talking that up in ‘63 and ‘65, when the first versions of the book came out. But by 1968, ‘69, ‘70, he certainly was, because the Whole Earth Catalog thing happened and I think environmentalists were clearly his people in a way that, perhaps, other science fiction writers were not.
Do you think that part of the reason Dune had mainstream success was because this environmental interpretation made it seem like more “serious” literature to readers who might not have picked up a sci-fi book otherwise?
Yes, absolutely. The reason why Dune is mainstream is because of the ecological messaging. And that’s not just true of the first novel, which is by far and away the most popular, but the thing also about Herbert is that he makes good on the idea that Dune is an ecological series in the sequels.
By the time we get to Children of Dune(1976), he has a very interesting message about climate change, which is that the sandworms are an endangered species but they’re also essential to the economy because they create the spice — the spice is an allegory for all natural resources that power transportation. So some of the best ecological messaging comes out of the sequels. Children of Dune was the first hardcover bestseller science fiction novel — in terms of being marketed as a science fiction novel — of all time. And in that book is when Herbert says, look, not only does climate change and ignoring climate change have a negative effect on our environment, but it has a negative effect on the economy as well.
Children of Dune is when Arrakis has been terraformed, like forced climate change. But it’s the reverse from us because instead of turning it into a worse environment, they’re actually making it more livable. But that is the thing that’s actually against the existing environment, and the thing that’s going to threaten to kill the sandworms and disrupt everything. So Herbert inverts the literalness by saying, Okay, this kind of forced climate change seemed like a great idea, one that the Fremen wanted, to transform it into a paradise. But now here we are, two books later, and not that much time has passed, and we’re looking at the extinction of the sandworms and the collapse of everything.
The environmental movement in the U.S. has changed a lot since Frank Herbert died in 1986. Were he still alive today, do you think he’d still be writing books with environmental themes? Or was it a passing fancy when it came to Dune?
No, no, he certainly would be. Absolutely. You could look at books like The Green Brain, and some of his other books, and definitely it’s there.
It’s interesting because you look at someone like Elon Musk — we all know there’s a political problem with Musk more broadly, and he’s almost like a character from Dune. Because he’s like, “I’m going to create all these electric vehicles,” but at what cost, right? Herbert was interested in political figures — Musk wouldn’t think of himself as a political figure, but he is — and the people with power who people don’t question. If we all agree that electric cars are good, then that would be Musk, right? But Musk is like Leto II, the God Emperor of Dune, and Leto II has ulterior motives in the end but so many people have to die to get there. So I think that if you could have Frank Herbert alive to see what’s going on with Elon Musk, he’d be like, “This is exactly what I was talking about.”
Is there anything else you’d like Heatmap readers to know about Dune?
What is really cool about Dune when it comes to its ecological messaging is that, like all good art, it is not an after-school special. That allows it to sink in more effectively. The irony that I point out in my book is that New World or No World is essentially an after-school special — it was literally on TV as a segment of people talking about the whole problem of climate change. [Reading from the book:] “I refuse to be put in a position of telling my grandchildren: ‘Sorry, there’s no world for you. We’ve used it all up.’ —Frank Herbert.” He is an environmentalist. But this book is not in print, and Dune is.
So why is Dune in print when we have to find that messaging? Because we have to find it: It’s not flashing on a giant sign like in Avatar or something like that. It’s not turning to the camera.
You look at something like Dune and you’ve got 60 years of people talking about it and thinking about it. And the “thinking about it” part is essential because people won’t change their minds with, like, a TV special. They will change their minds with a novel. A novel, a story, can move people.

Can Musk pull another market miracle out of his MAGA hat?
It’s long been clear that Elon Musk’s primary talent is not dreaming up electric cars, reusable rockets, or tunnel-boring machines. It is reshaping reality in a way that always seems to keep Tesla’s stock price high, which made him the world’s richest man.
That stock price has been taking a beating of late. A groundswell of Tesla resentment has arisen since Musk hitched his wagon to Donald Trump and began dismantling the American government. Public rage has taken the form of protests, vandalized Superchargers, and, most importantly to the man himself, sliding sales of Tesla vehicles. All of this has combined to send the company’s market value tumbling this year, to the delight of Musk-haters everywhere eager to see his net worth implode. Its share price has fallen more than 5% today alone.
Even so, Musk carries on as Trump’s right-hand man as if his fortunes are immune from Tesla’s ups and downs. Could this time be different?
Tesla saw plenty of dark times during its march to EV dominance, such as the notorious “manufacturing hell” needed to bring the Model 3 to fruition. Likewise, there have been plenty of times when Tesla’s soaring stock valuation appeared to be untethered from its business reality — it became the world’s most valuable automaker while building only a tiny fraction as many cars as Toyota or General Motors.
The difference in those days was that Tesla — current profits and losses aside — was clearly on the rise. Overcoming that manufacturing problem, for example, allowed the EV-maker to build lots and lots of Model 3s and Model Y and put it on the path to worldwide electric car dominance. Today that upward trajectory is not so clear. Tesla sales in the U.S. plateaued last year even before Elon’s misadventures with MAGA. This year, sales in Europe and Australia are in freefall, seemingly in response to Musk’s embrace of the far right. Tesla is down 71% this quarter in Germany and Australia.
It would be easier for Tesla to cast this dip as a blip if something new and exciting were waiting right over the horizon. But the only new vehicle to arrive since 2020 is the Cybertruck, the metallic embodiment of Musk’s conversion on the road to Mar-a-Lago. The brand’s biggest hope for improving sales is the recently revealed redesign of the Model Y, code-named “Juniper,” which follows a similar update to the Model 3.
The company’s future is pegged not to any new EV with widespread appeal, but rather to the notion that Tesla will solve autonomous driving and dominate the next automotive era with its Cybercab and similar self-driving vehicles. Whether Musk will actually win the future is beside the point. What it achieves in the present is freeing Musk from being judged on hard sales numbers like an ordinary car company CEO and keeping him in the character of visionary innovator, able to keep his stock price afloat through his own genius.
That doesn’t mean Musk can dismiss the power of dollars and cents with a wave of his hand. Investors are once again furious with the CEO for taking a ketamine-powered journey into the abyss rather than trying to build Tesla’s business in a practical way. And even if he can keep their anger at bay, a sales tumble really is a multi-pronged problem for Tesla.
For one thing, Musk’s political machinations have cost him all the market gains he earned via Trump’s electoral victory. Tesla’s valuation soared from around $800 billion to $1.5 trillion in December, when it became clear the CEO would become the president-elect’s right hand man. Since that moment, the company’s value has fallen by more than $600 million, effectively erasing the bump in Tesla’s market cap.
Still, Tesla — and Musk by extension — remains incredibly valuable. The carmaker’s true concern is that a big drop in sales could be a double-whammy for Tesla revenue. Recall that the company’s most reliable revenue stream is not really its sales of electric cars, but rather the carbon credits generated by those EVs under California’s auto emissions regulatory scheme, which it can sell to other automakers who’ve yet to meet their emissions targets. Even as Tesla’s reputation foundered in 2024, its revenue stream from selling credits reached $2.76 billion, up 50% from 2023.
That stream of free money helps to stabilize Tesla’s balance sheet in times of trouble. It is not inevitable. If automakers like Stellantis got their act together and started to sell a high volume of low-emissions vehicles, they’d need to buy fewer credits from Tesla. Tesla’s tumbling sales in the wake of Musk’s antics could reduce the amount of credits it could sell to others, since the credits are tied to sales of low-emissions vehicles. And it’s not out of the question that Musk’s political ally, President Trump, could attack the carbon market as part of his offensive against EVs, which could eliminate this revenue stream for Tesla. (If this seems unlikely, consider that Musk pursued this alliance knowing full well that Trump campaigned on eliminating federal tax credits for EVs that benefit Tesla buyers.)
Even with this dire financial picture, it’d be foolish to bet against Musk. The man has overcome more harrowing market conditions — and that was before America’s unelected chief consultant managed to entrench himself as Hand of the King. But seeing his supply of easy money wither because of his political stances might be just the thing to hit the man where it hurts.
On exemptions, lots of new EVs, and Cyclone Alfred
Current conditions: A smattering of rainfall did little to contain a massive wildfire raging in Japan • Indonesia is using cloud seeding to try to stop torrential rains that have displaced thousands • At least 22 tornadoes have been confirmed this week across southern states.
The Trump administration said yesterday that automakers will be exempt from the new 25% tariffs on imports from Mexico and Canada – but just for a month. The announcement followed a meeting between administration officials and the heads of Stellantis, GM, and Ford – oh, to be a fly on the wall. As Heatmap’s Robinson Meyer explained, the tariffs are expected to spike new car prices by $4,000 to $10,000, and could hit internal combustion cars even worse than EVs, and prompt layoffs at Ford and GM. “At the request of the companies associated with [the United States-Mexico-Canada Agreement], the president is giving them an exemption for one month so they are not at an economic disadvantage,” Trump said in a statement. Stellantis thanked Trump for the reprieve and said the company “share[s] the president’s objective to build more American cars and create lasting American jobs.” Around 40% of Stellantis cars currently sold in the U.S. are imported from Canada and Mexico.
The Supreme Court has rejected President Trump’s request to withhold roughly $2 billion in congressionally-approved payments to the U.S. Agency for International Development for foreign aid work that has already been completed. On his first day back in office, Trump ordered a 90-day pause on all foreign aid so programs could be reviewed to ensure they align with his agenda. The administration then eliminated funding for the majority of USAID’s contracts, including at least 130 that related to climate and/or clean energy. This week’s SCOTUS decision was “a welcome but confusing development for humanitarian and development organizations around the world,” The New York Timesreported, “as they waited to see if thousands of canceled contracts would be restarted.”
Speaking of cars, there has been a lot of EV news in the last few days:
Rivian announced plans to expand internationally. CFO Claire McDonough also said the company is working “around the clock” to roll out the new R2, R3, and R3X models, with production for the R2 set to start early next year. She said international expansion plans would kick off after the R2 production ramps up.
Volkswagen unveiled the ID. EVERY1. The concept-car version of its ultra-affordable EV “will be the first to roll out with software and architecture from Rivian,” TechCrunchreported. Production is slated for 2027, and the car will start at around 20,000 euros (or $21,500). No word on a U.S. release, though.
The ID. EVERY1Volkswagen
Volvo showed off the ES90. What is it? Good question. “Some might say it is a sedan,” the company said in its press release. “Others will see a fastback, or even hints of an SUV. We’ll let you be the final judge – all we know is that the new, fully electric Volvo ES90 carves out a new space for itself by eliminating the compromises between those three segments, which puts it in a class of its own.” InsideEVscalled it the company’s “most advanced EV to date,” because it can charge for 186 miles of range in 10 minutes on a fast charger.
Cadillac introduced a very long electric SUV. The electric Escalade IQL will go into production this year. With an overall length of 228.5 inches, it will be the longest SUV, uh, ever. It’ll start at $132,695.
On a related note, Tesla sales continue to plummet worldwide. They were down 76% last month in Germany, with sharp declines across other European countries, too. In Australia, sales were down 72%.
Global sea ice levels were at an all-time low last month, according to researchers at the Copernicus Climate Change Service. Arctic sea ice cover was 8% below average in February, the lowest since records began in 1979, and “the third consecutive month in which the sea ice extent has set a record for the corresponding month.” Antarctic sea ice cover was 26% below average. “One of the consequences of a warmer world is melting sea ice, and the record or near-record low sea ice cover at both poles has pushed global sea ice cover to an all-time minimum,” said Samantha Burgess at the European Centre for Medium-Range Weather Forecasts. Melting sea ice contributes to sea level rise and ocean acidification, harms polar ecosystems, and creates a global-warming feedback loop by reducing albedo, which is the Earth’s ability to reflect sunlight back to space.

Forecasters are growing increasingly concerned about Cyclone Alfred, which is swirling off the coast of eastern Australia and is expected to arrive Friday or Saturday as a category 2 storm, or perhaps even a category 3. Alfred will be the first cyclone in 50 years to make landfall in this part of Australia. The storm has slowed as it approaches land, which means it will spend more time over very warm waters, soaking up even more moisture to dump on land. “The northeastern Coral Sea, where Cyclone Alfred formed, experienced the fourth-hottest temperatures on record for February and the hottest on record for January,” a group of climate change researchers wrote at The Conversation. Residents in and around Brisbane have been told to prepare to evacuate.
American drivers spent more time on the road last year than ever before, logging a record 3.28 trillion miles.
On boasts and brags, clean power installations, and dirty air
Current conditions: Strong winds helped spark dozens of fires across parched Texas • India’s Himalayan state of Uttarakhand experienced a 600% rise in precipitation over 24 hours, which triggered a deadly avalanche • The world’s biggest iceberg, which has been drifting across the Southern Ocean for 5 years, has run aground.
President Trump addressed Congress last night in a wide-ranging speech boasting about the actions taken during his first five weeks in office. There were some familiar themes: He claimed to have “ended all of [former President] Biden’s environmental restrictions” (false) and the “insane electric vehicle mandate” (also false — no such thing has ever existed), and bragged about withdrawing from the Paris climate agreement (true). He also doubled down on his plan to boost U.S. fossil fuel production while spouting false statements about the Biden administration’s energy policies, and suggested that Japan and South Korea want to team up with the U.S. to build a “gigantic” natural gas pipeline in Alaska.
On the same day as the speech, new tariffs on imports from Canada, Mexico, and China came into effect, triggering retaliatory duties and causing stock markets to plunge. Experts are busy trying to figure out what it all means for American businesses and consumers. As Heatmap’s Robinson Meyer explained, the tariffs are likely to make electricity prices go up, raise construction costs, make gas more expensive at the pump, and make new cars costlier. Fossil fuel firms aren’t thrilled. The American Gas Association said the 10% tariff on Canadian natural gas “indicates potential impacts totaling at least $1.1 billion in additional costs to American consumers per year.” Chet Thompson, CEO of the American Fuel & Petrochemical Manufacturers, said that “imposing tariffs on energy, refined products, and petrochemical imports will not make us more energy secure or lower costs for consumers.”
Commerce Secretary Howard Lutnick has implied Trump might lift these tariffs as soon as today, but TBD.
The Trump administration has ended a program that monitored the air quality at more than 80 U.S. embassies and consulates around the world, citing “budget constraints.” The program started in 2008 with the U.S. embassy in Beijing and expanded from there. The data collected, which was posted on the AirNow website, has been used in academic studies and credited with helping reduce pollution levels in the host countries, leading to better health outcomes. This move “puts the health of foreign service officers at risk” and could hinder research and policy, Dan Westervelt, a research professor at Columbia University’s Lamont-Doherty Earth Observatory, toldThe New York Times.
Clean power installations soared in the fourth quarter of 2024, sending total operational capacity above and beyond the 300 gigawatt mark, according to a new report from the American Clean Power Association. “It took more than 20 years for the U.S. to install the first 100 GW of clean power, five years to install the next 100 GW, and three years to install the most recent 100 GW,” the report says. Here are some takeaways:

China plans to ramp up its efforts to rein in emissions, expanding its emissions trading system beyond power plants to to include industries such as steel, aluminum, and cement, Premier Li Qiang said in a report this week. “Li also confirmed China intends to continue to play a key role in diplomacy on emissions reduction, as the U.S. retreats from international cooperation,” Bloombergreported. The country plans to roll out major climate projects such as offshore wind farms, “new energy bases” across its deserts, with a goal of reaching peak emissions before 2030. China is the world’s largest emitter of greenhouse gases, and while it has been rapidly expanding renewable power generation, it also struggles to wean itself off coal.
The Supreme Court yesterday watered down the Environmental Protection Agency’s authority to regulate water pollution, siding with the city of San Francisco in an unusual lawsuit pitting the liberal hub against the environmental authority. In a 5-4 decision, the justices said the agency had overstepped its authority under the Clean Water Act when it issued permitting for a San Francisco wastewater treatment plant that empties into the Pacific. The permit included provisions that would have made San Francisco authorities responsible for ensuring the water quality in the Pacific met EPA standards. Justice Samuel Alito essentially wrote that the permitting rules were too vague. “When a permit contains such requirements, a permittee that punctiliously follows every specific requirement in its permit may nevertheless face crushing penalties if the quality of the water in its receiving waters falls below the applicable standards,” Alito wrote. The ruling will make it harder for the EPA to limit water pollution. Next up on the SCOTUS docket: nuclear waste!
Bernard Looney, the former CEO of oil giant BP, is the new boss of an AI startup that tells businesses how to cut their emissions.
